| 重力勘探在矿产勘探中被广泛用于探测地下密度的变化，这些变化可能指示潜在的矿化带或成矿构造。本文对内蒙古下都伦胡东地区布格重力异常数据进行了系统处理与分析，采用位场数据处理技术，包括向上解析延拓、剩余重力异常提取和垂向二阶导数计算等方法。重点研究了欧拉反褶积法的理论基础，详细推导了其数学模型，并探讨了该方法的应用优势及局限性。通过单体模型试验，对比分析了不同构造指数对反演结果的影响；组合模型试验验证在有干扰场源的情况下，欧拉反褶积的适用性。最终，基于欧拉反褶积法对研究区断裂构造进行了精细解释，识别出一条区域性深大断裂和数条次级断裂，并据此圈定了 6个具有找矿潜力的成矿远景区。综上所述，本研究不仅系统验证了欧拉反褶积法在复杂地质条件下的适用性与有效性，也为内蒙古下都伦胡东地区断裂构造识别与成矿远景预测提供了可靠的地球物理依据，对区域矿产勘查部署具有实际指导意义。 |

| Gravity exploration is widely utilized in mineral prospecting to detect subsurface density variations,which may indicate potential mineralization zones or ore-forming structures. This study systematically processed and analyzed the Bouguer gravity anomaly data from the Xiadulunhudong area of Inner Mongolia, employing poten-tial field data processing techniques including upward continuation analysis, residual gravity anomaly extraction,and vertical second derivative calculation. The research focused on the theoretical foundations of Euler deconvolu-tion, deriving its mathematical model in detail while discussing the method′s advantages and limitations. Throughsingle-source model tests, the influence of different structural indices on inversion results was comparatively ana-lyzed. Combined-source model experiments further validated the applicability of Euler deconvolution under sce-narios involving interfering field sources. Ultimately, based on Euler deconvolution, the fracture structures in thestudy area were meticulously interpreted, identifying a regional deep-seated fault and several secondary faults.These findings led to the delineation of six prospective metallogenic zones with mineral exploration potential There-fore, this work demonstrates the utility of Euler deconvolution in complex geology and provides a robust geophysicalbasis for delineating fault structures and identifying promising mineralization targets in the study area, with directimplications for guiding future mineral exploration in Inner Mongolia. |
